    What is sodium formate? 

    Sodium formate is a formic acid salt that contains sodium. Its formula is HCOONa, with sodium replacing one of the hydrogens in formic acid, HCOOH. At room temperature, the chemical usually looks like a white, slightly opaque powder. Sodium formate powder absorbs moisture from the environment, so it’s recommended to store it in airtight containers in cool, well-ventilated places away from moisture. 

    Sodium formate, HCOONa (CAS Number 141-53-7), is the sodium salt of formic acid, HCOOH. It usually appears as a white deliquescent powder. Molar mass, 68.007 g/mol. Sodium formate is a salt of a weak acid Formicacid and a Strong base Sodium hydroxide. It belongs to the class of organic compounds known as carboxylic acid salts. These are ionic derivatives of carboxylic acid. It is soluble in water and formic acid.

    In general, formic acid is widely recognized as a very effective feed acidifier and antimicrobial agent. However, it can be challenging to decide whether to use a formic acid or a sodium formate. The key difference between sodium formate and formic acid is that, the hydrogen ion of the functional group has been exchanged for a sodium ion (Na+), forming a salt. As sodium formate is very soluble in water it will be rapidly dissolved into sodium (Na+) and formate ions (HCOO-).
    In effect, this means that whether you add formic acid or sodium formate, at a pH below 3.75 the majority of the molecule will be available as formic acid (HCOOH). The converse is also true, at pH above 3.75 the majority will be available as formate ion (HCOO-).

    Sodium formate is used as a reagent for both arsenic and phosphorous. It can also act as a buffer when working with mineral acids. Beyond research applications, sodium formate is used as a preservative and a component of several heavy industrial materials, including adhesives, paints, explosives and certain high-grade lubricants. Sodium formate is used as a component in the preparation of Urine Maintenance Fluid. In the food industry it is a preservative. Its use in the leather industry as an acid camouflage for chrome tanning. Stabilizes skin collagen as a mineral or vegetable tanning agent, transforming it into leather, helping to fix chromium salts and generating a low pH effluent at the end of the stage. Granular sodium formate (NaCOOH) is a popular deicer used at airports. It is mainly used to weaken compacted snow/ice and thereby facilitate mechanical ice removal.



    Is sodium formate hazardous?

    Yes, this chemical can present a certain level of danger if proper safety protocols are not followed. Sodium formate can cause harm if you swallow or inhale it. The chemical can also irritate your eyes, skin, and respiratory tract, causing you to develop a cough, sore throat, and feel short of breath for seemingly no reason. You should always follow proper safety precautions when working with this reagent.


    Is sodium formate flammable?

    No, sodium formate is not flammable. However, it can form dust in the air that can spontaneously combust when a source of ignition is present.
